I think it’s the cam chain. Could it be a bearing? It has a little over 14K miles on it. I don’t think it has ever been opened up. It had 6K on it when I got it.

First things first, check the cam chain adjustment.

May be the cam chain. The rubber parts.

Or a valve play adjuster coming loose .

It sounds like a bearing failure. I’ll post in this thread with the forensics.
I feel the pain. I'm not sure if that's camchain or not.
Sounds like it's dry, can you verify it's getting oil on top? 
Worth a look. Best of luck.

There’s a bike event coming up in Vicksburg on Nov 1. I’m prioritizing two other bikes. This one however seems to be my favorite.
How many miles on it? Is this the one you topped when it was using oil at the Stekoah rally?
Screwdriver/stethoscope to try and locate source of the noise?
No. This bike had 6,000 miles when I got it but it was a pile of parts. It was a father/daughter project. She moved on. https://www.xs650.com/threads/reunited-with-xs650sh.63667/ I never opened the engine. It now has a little over 14,000 miles.
@Raymond, I think I may have a couple of things going on. There’s a ringing knock that sounds like cam chain guide. There’s also a noise that sounds like gravel in the engine. The latter noise abruptly starts and stops. I can hear it come on and off at speed up to 50 mph. I think it sounds like the countershaft bearing, but that’s only because I just found the 36 mm nut loose and subsequently torqued it to 90 ft lbs then hit the road.
Right before departure I replaced rear tire, engine oil, generator brushes and tq’d that nut. I fully expected nothing could go wrong.
The former “tar baby” would likely have been the better choice.
Hindsight is 20/20
@desmoman900 is carrying this bike back to the Temple of Speed in Georgia. He will update this thread.
Could it be a tappet adjuster locknut?
It’s been a while, but I’m pretty sure I pulled those covers and checked in the hotel parking lot.
Sure toss it off on poor ole Joào. His life is hard.
